SPECIFICATION orming part of Letters Patent No. 545,286, dated August 27, 1895.

Ap lication filed January 14; 1895. Serial No. 534,785. (No model.)

T all whom it may concern:

Be it known that we, VVILLIAM GUTEN- KUNST and CHARLES A. GUIENKUNST, citi zens of the United States, residng at Milwaukee, connty of Milwaukee, State of Wisconsin, have invented a certain new and useful Improvement in FeedRollers; and we declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Our invention relates to new and useful improvements iu the construction of feedrollers for feed-cutters, cormhuskers, and machines of similar nature, and our said invention consists in the matters hereinafter described, and pointed out in the appended claims.

In the accompanying drawings illustrating our invention, Figure 1 is a broken side elevation of a pair of feed-rollers constructed in accordance therewitn. Fig. 2 is a vertical transverse section of the same, taken on line 2 2 of Fig. 1.

Heretofore it has been found that in the operation of corn-husking machines, feedcutting machines, or other machines Operating upon long material, such as cornstalks or the like, the long leaves of the corn or other material often become twisted or wrapped around the feed-rollers and materially nterfere with the feeding of material into the machine. Fnrthermore, it often happens that in stripping the cars of corn from the stalks the stalk or part of the husk will enter between the feed-rollers and the ear of cornwill come into contact with the faces of the rollers and will bang in this position, the stalk or the husk being loosely grasped by the rollers and not pulled away from the ear. This greatly interferes with the operation of the machine and With the feeding of material the1eto.

It is the object of our present invention to construct an improved form of feed-rollers which will effectually obviate the aforesaid difficulties and at the same time will insure the satisfactory feeding of the material to the machine.

To this end we construct our improved feedrollers in substantially the manner illustrated in the drawings, said rollers being provided with intermeshing teeth of a construction to be presently described.

We prefer in practice to construct the rollers from interior axial shafts A A of machinesteel, and exterior toothed portions B B of chilled-iron or highly-tempered steel fitted thereto. At opposite ends of the exterior toothed portions B B are provided annular raised bearing-faces C C, arranged to have a rolling contact with each other when the rollers are in operation. These raised annular faces C C serve to hold the rollers apart to a desired extent. Upon each rollerare arrangcd a plurality of r0ws of teeth, the teeth being constructed substantially as shown in the drawings and arranged so as to break spaces over the entire surfaces of the rollers.

The teeth D D of one or more of the rows upon each roller are made of just sufficient height to enable them to touch the surface of the cylindric body of the opposed roller, and the teeth E E of the other rows upon each roller are made somewhat shorter, so as to aiford considerable clearance between them and the cylindric face of the opposed roller.

The arrangement of the teeth upon the working surfaces is such that the teeth forming the rows upon each roller break spaces with each other, both longitudinally and circumferentially of the r0llers, throughout the surfaces of the rollers.

The rollers are arranged and geared together, so that when revolved the teeth of either roller will mesh with the teeth upon the other or opposed roller, said long, or high teeth D D in the rotation of the rollers pressing upon the cylindric face of the opposed roller in the manner described. By this con struction, as the material is fed into the machine it is engaged by the teeth upon the faces thereof and drawn between the rollers in an Obvious manner, and any long and flexible blades or leaves that would be likely to coil or wrap around the rollers will be cut or pinched in two between the cylindric faces of the body portions of the rollers and the faces or tops of the high or long teeth D D. This effectually prevents the material from IOO coiling or wrapping around the feed-rollers and clogging or interfering with the operation of the rollers. By this construction, in case an car of c0rn should become lodged, in the manner described, in front of the feedrollers, so as to be held in contact therewith by the grasp of the rollers on the stalk or husk, the long or high teeth D D of either roller will, when they come against the cylindric face of the opposed roller, operate to cut or pineh off the stalk or husk orto tear the same from the ear of corn, so as to free the car and permit it to drop.

By the arrangement of the annular raised bearing-faces C C, as described, the rollers are held apart so as to take all strain or pressure off fron1 the teeth D D and prevent wear thereof, said teeth being permitted to just touch the cylindric faces of the opposed roller, so as to perform the operation of cutting or pinching off the material.

By reason of the described construction of the rollers with the tool-steel central shafts AA and the exterior chilled or highlytemdered portions the rollers are rendered very durable and substantial, the tough tool-steel centers affording the necessary'strength and the hard outer portions resisting wear.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent of the United States, is

1. A pair of feed rollers each provide With one or more rows of long or high teeth, and With intermediate blank spaces and hav j ing the remainder of its surface provided with shorter or lower teeth, and said teeth being arranged in a generally quincunx order over the entire surface of said roller, and said rollers being gcared together so as to bring the teeth of each roller into 1nesh both longitudinally and circumferentially With the teeth of the opposed roller, and said long or high teeth on each roller being arranged to enter the spaces between the long or high teeth of the opposed roller, and to engage with the cylindric surface of said opposed roller, substantially as described.

2. A pair of feed rollers each provided With rons of teeth, the teeth forming the several rows being arranged so as to alternate lengthwise and circumferentilly of the rollers, and the teeth of one or more of the rows on each roller being made longer or higher than the teeth of the other rows, and adapted to bear against the cylindric body of the opposed roller, said rollers being geared together se as to bring said teeth into mcsh both longitudinally and cireumferentially of the rollers, and raised annular bearing faces at opposite ends of said rollers adapted forengagernent with each other, substantially as and for the purpose described.

An improved feed-roller comprising a central shaft of tool-steel or analogous tough material, and an ext pr portion of chilled or highly ten provided with rows of gn v one or more-rows of cuttin Longer or higher than said grasping teeth, substantially as and for the \purpose described.

\ In testimony whereof we sign this specifio n in the presence of two witnesses.
